Self-assured Madison Avenue ad exec Roger Thornhill (Grant) inadvertently gets involved with international spies when they mistake him for someone else. His problems are compounded when he's framed for murder and winds up on a cross-country train trip with pretty Eve Kendall (Saint) who offers her help. The movie where Grant and Saint dangle from the faces of Mount Rushmore and a plane chases Grant through farm fields. Exceptional performances, particularly Grant's. Plenty of plot twists are mixed with tongue-in-cheek humor.
